A novel process for the preparation of a fluorolactone derivative of the formula
and of its acylated derivative of formula
wherein R
1
stands for a hydroxy protecting group is described.
The acylated fluorolactones of formula V, particularly the benzoyl derivative with R
1
=benzyl are important precursors for the synthesis of prodrug compounds which have the potential to be potent inhibitors of the Hepatitis C Virus (HCV) NS5B polymerase.
一种制备氟内酯衍生物的新工艺被描述,其化学式为,以及其酰化衍生物的化学式为,其中R1代表一个羟基保护基团。化学式为V的酰化氟内酯衍生物,特别是具有R1=苄基的苯甲酰衍生物,是合成前药化合物的重要前体,这些前药化合物具有成为HCV NS5B聚合酶的强效抑制剂的潜力。
